A particle is moving along a vertical circle of radius `R=20 m` with a constant speed `v=31.4 m//s` as shown in the figure. Straight line `ABC` is horizontal and passes through the centre of the circle. A shell is fired from point `A` at the instant when particle is at `C`. The distance `AB` is `20sqrt(3)m` and shell collides with the particle at `B`, if smallest possible value of the angle of projection is `k xx 10^(@)` then find the value of `k`.

A particle is moving along a vertical circle of radius r = 20 m with a constnat vertical circle of radius r = 20 m with a constnat speed v = 31.4m/s as shown is figure . Straight line ABC is horizontal and passes throught the centre of the circle . A shell if fired from point A at the instant when the particle is at C. If distance AB is 20sqrt(3) m and the shell collide with the particle at B , then prove tan theta = ((2 n -1)^(2))/(sqrt(3)) .where n is an interger. Further , show that smallest value of theta is 30^(@) .
